I UNITED 'STATES PATENT OFFICEO l JAMES SUTHERLAND, OF EASTHAMPTON, MASSACHUSETTS, ASSIGNOR TO HIMSELF AND JOS. MUMFORD, OF SAME PLACE.

Specication forming part of Letters Patent No. 55,211, dated May 29, 1866.

To all whom it may concern:

Beit known that I, JAMES SUTHERLAND, of Eastham pton, Hampshire county, Commonwealth of Massachusetts, have invented a new and useful Improvement in Spinning and Twisting Frames; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to letters of reference marked thereon.

This invention consists in a peculiar and .economical manner of transmitting power from the horizontal drum to the sets of spindles on each side, and in a peculiar arrangement of the drum and spindles to accomplish this purpose.

The construction and arrangement of this improvement I will now describe.

In the drawings, Figure l is a side view of a frame arranged according to my invention. Fig. 2 is a plan view of the same with the top removed, so as to show the arrangement ofthe drum and spindles.

A is the drum, and a, a, Ste., b b, Ste., the spindles, similar to the ordinary drum and spindles. B B is the frame supporting the same. Power is applied at C to turn the drum, and is conveyed by means of the bands c o, &c., to the spindles; and it is in the arrangement of these bands c c that the principal feature of this invention consists.

It has been customary heretofore to drive the spindles from the drum by means of quarter-turn belts passing from the former t0 the latter. This necessitates a wide frame and giooved pulleys on the spindles, in order that..

the belts may not slip off, and is a very uneconomical method of applying power from this circuinstance-namely, in passing to the pulleys on the spindle from the drum the belt strikes the former at an angle, and the pulley being grooved the belt strikes a part of the pulley which is 0f greater diameter than the central part, by which the belt drives it, and consequently it (this part of the pulley, marked g in the drawings) must revolve faster than the central part, or, rather, go through more space in the same time, and acts'as a brake on the cord, which it requires a considerable force to overcome in the aggregate throughout the machine, and it is the object of my invention to obviate this diiiiculty, doing away entirely with these quarter-turn belts, and working the machine entirely with straight belts. To accomplish this I first place the drum in the frame, raised up so much higher than ordinarily used Vas that the top or bottom of the drum may come on a line with the centers of the spindle-pulleys. I then pass a single band, as shown in the drawings, iirst around one pulley, a, then across under the drum to the pulley b on the opposite side of the frame, then around this pulley b, and under and around the drum, and back to the pulley a again, thus forming a belt which runs directly to the spindles on each side. The spindles in each row are placed at equal distances from each other; but the spindles b are not set directly opposite the spindles a, but are so set that each spindle comes opposite the space between the spindles in the opposite row, as shown inthe drawings. This is done in order to prevent the belts running together.

I gain by this invention a large amount of power, amounting practically to more than one-half, as I have found by actual experiment that I can drive a frame which as ordinarily arranged requircs a belt of three inches in width with a belt of only one and one-quarter inch width.

Now, having described my invention, what l claim as new, and desire to secure by Letters Patent, is-

The combination of the drum A, spindles a a b b, and bands o c, the whole arranged and operatin g in the manner and for the purpose herein described.

JAMES SU TH ERLAND.
